spring.http.multipart.maxFileSize prompt invalid error Problem

In SpringBoot project, configure spring.http.multipart.maxFileSize used to define the maximum file upload size.

However, unlike SpringBoot version, configuration on this one is not the same.

 

1, Spring Boot 1.3 version:

　　multipart.maxFileSize

 

2, Spring Boot 1.4 version and 1.5 version:

　　spring.http.multipart.maxFileSize

 

3, Spring Boot version 2.0:

　　spring.servlet.multipart.maxFileSize

 

Above, pay attention to the difference between versions 1.4, 1.5 and 2.0 versions, has been or will prompt invalid.

 

Attached  application.yml  configuration:

spring:
  servlet:
    multipart:
      enabled: true
      max-file-size: -1
